    Product Features 

    • The BY08IIDC-40 Series T2 DC Surge Protective Device (SPD) is designed to protect photovoltaic systems, specifically used in string boxes and inverters, from electrical surges and transients. This surge protective device comes in 2P and 3P configurations and is engineered to handle DC circuits with voltage ratings of 600VDC, 1000VDC, and 1500VDC, making it highly versatile for various solar power installations.
    • Equipped with high-energy Metal Oxide Varistor (MOV) technology, the BY08IIDC-40 series SPD is capable of effectively clamping high-voltage surges and dissipating excessive energy. This advanced MOV technology ensures rapid response to over-voltage events, preventing damage to sensitive equipment. The device is rated to handle discharge currents ranging from 20kA to 40kA, providing robust protection against large surge events such as lightning strikes or electrical grid disturbances.
    • The primary function of the BY08IIDC-40 series SPD is to safeguard critical components in photovoltaic systems, such as inverters and string boxes, from transient over-voltage conditions that can cause irreparable damage. By redirecting excess electrical energy safely to the ground, this device helps maintain the operational integrity of the solar power system, ensuring long-term reliability and performance.
